BILL-FILE.

SPECIFICATION forming part of Letters Patent No. 274,729, dated March 27, 1883.

Application filed January 24, 1883. (No model.) i

To all whom it may concera:

Be it known that I, MARCUS J. DAVID, a citizen of theUnited States, residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Bill-Files, of which the following is a specification.

This invention consists in the combination, with a suitable base, of a rod firmly secured in the down wardly-projectin g ends of the base a a pin which extends through a slot in the base and is provided with an eye embracing the rod; a spring which is coiled round the rod and provided in its middle with a loop bearing on the pin, while its ends bear against the bottom surface of the base, and an abutment or pin-holder rising from the base, so that 'by the action of the springthe pointof the pin is held up against the pin-holder, and when a bill is to be filed the pin can be easily pressed back against the action of the Spring.

This invention is illustrated in the accompanying drawings, in which Figure l represents a perspective view. Fig. 2 is a sectional front view. Fig. 3 is a transverse section in the plane a: m, Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the base of my bill-file, which is made of cast-iron, or any other suitable material, and provided at its sides and ends with downwardly-projecting flanges or rims a, so as to form a concave space beneath. In this concave space is situated arod, B, which is firmly secured in the down wardly-projectin g ends a, at some distance from the under surface of the base A. ()n this rod are mounted a' series of pins, 0, which project through slots b in the base A, and are provided at their bottom ends with eyes 0, emhracingthe rod B, so that they can swing as far as the slots b will permit.

With each of the pinsG iscombined a spring, D, which is coiled round the rod B, half in one direction and half in 'the opposite direction, and provided in its middle with a loop, at, which bears upon the shank of the pin, while the ends of said spring bear against the under surface of the base A. By coiling the spring onehalf in one direction and the other half in the opposite direction both portions of the spring wind up, if the loop dis pressed outward to the position shown in full lines in Fig. 3, and as the spring has a natural tendency to unwind, the loop 01, which bears upon the shank of the pin 0, throws said pin forward to the position shown in dotted lines in Fig. 3. In this position the point of the pin bears against an abutmentor pin-holder, E, which rises from the base A,andisfirmlysecuredinthesame. Thisabutment is by preference made in the form of a hook,of wire, equal in thickness tothe pin, and the end of said hook is provided with acavity to receivethe point of the pin, as shown in the drawings.

By means of the slots 1; in the base the pins are prevented from sliding on the rod B in the direction of its length, and the springs are retained in position by the pins; but, if desired, the end coils of each spring may be fastened to the rod B by solder or other suitable means.

It will be readily understood that the number of pins mounted on the rod B may be increased to any desired extent.

. What I claim as new, and desire to secure by Letters Patent, is--.

The combination, substantially as hereinbefore described, of the base A, provided with the abutmentor pin-holder E, the rod B, firmly secured in the downivardly-projecting ends of said base, the pin 0, which extends througha slot in the base and is provided with an eye embracing the rod B, the spring D, provided in its middle with a loopwhich bears upon the shank of the pin, said spring being wound half in one and half in the opposite direction, and having its ends brought to bear against the under surface of the base, and serving to retain the pin against the abutmentor pin-holder, and to restore it back against the said abutment or holder when drawn therefrom and released.

In testimony whereofl have hereunto set my hand and seal in the presence of two subscribing witnesses.
